Under-reamed piles and Capping beam
Under-reamed piles are a type of deep foundation system that is commonly used in civil engineering projects. These piles are specifically designed to provide a stable and strong foundation for structures. The under-reamed piles are connected by a beam known as a capping beam.
What are under-reamed piles?
Under-reamed piles are cylindrical in shape and are typically made of reinforced concrete. They are installed by drilling a hole into the ground and then expanding the bottom portion of the pile to create a larger diameter. This enlarged portion is known as the under-ream, and it serves to increase the bearing capacity of the pile.
Why are under-reamed piles used?
Under-reamed piles are used in situations where the soil conditions are not suitable for shallow foundations. They are especially effective in areas with loose or weak soils, as the under-reamed portion of the pile provides increased lateral resistance and prevents the pile from sinking or tilting.
What is a capping beam?
A capping beam is a horizontal structural element that is used to connect and support the tops of multiple piles. It is typically made of reinforced concrete and is designed to distribute the load evenly across the piles. The capping beam serves to increase the overall stability and strength of the foundation system.
Why is a capping beam used with under-reamed piles?
The capping beam is used to connect the tops of the under-reamed piles and create a unified foundation system. It helps to transfer the load from the superstructure to the piles and provides additional lateral support. The capping beam also helps to distribute the load evenly across the piles, reducing the risk of differential settlement.
Conclusion
In conclusion, under-reamed piles are connected by a beam known as a capping beam. This beam serves to connect and support the tops of the piles, providing additional lateral support and distributing the load evenly. The use of a capping beam increases the stability and strength of the foundation system, making it an integral component of under-reamed pile foundations.
